Referring to Figs. 1 and 2,1 generally indicates a closed casingprovidedwith the refractory and heat insulatinglining and enclosing theinclined, perforated wharf 5,

which positioned above the bottom of the casing so asto provide thespace orcha'mber 4 beneath the wharf.

cThe wharf is preferably made up, offthe under lapping plates "5,havinginterstices between them forming passages leading from the spacebelow the wharfto that; above.

I The casing is provided withthecharging opening 6 at the high end oftheWh-arf, and

its gas tight closure 7, which in theap'paratus shown .is water sealed.he casing-is also provided with the discharge opening 8 atfthe low end.of the wharf, providedwith theflgas 4 "tight door or gate' 9'. Y

- In operation, a charge of hot coke is ad I initted through the opening6, the door 9fbedistributes itself in a quiescentlayer over the wharf.The opening, 6 is closed 'andthe fair within the apparatus is circulatedand recir culated by the fan, throughthe wharf,'c0ke f f and boiler.After one or two passages through the coke the airv is spent by comb'ustion of asmall amount of coke and thef fur ther circulation is of theseproducts are inert to the coke;

' During the p'assageof the gas throughthe coke, it" becomes heatedthereby co'oling the V coke; and during its passage 'throughthe I boileris becomes cooled, giving upfits heat, K

chamber is somewhat enlarged as by the provision of the wall 29. Thereare also progas is terminated, the door 9 is opened'and the batch ofcoke slides gently down off the Wharf and out of the apparatus.

The fire tube boilers may be of standard type which can be manufacturedeconomically. Moreover, they can be made inthe shop and shippedassembled, whichreduces the necessary construction in the field.

The apparatus is compact and simple,

economical of construction, efficient in operation and of high capacity.It combines the more economical construction of the fire tube boiler,with the high rate of cooling secured by combined recirculation of gasand direct radiation, and includes the gentle handling of the coke andlow breeze production inherent in the wharf type cooler.

- The construction and mode of operation of the modificationillustratedin Fig. 3 are as has been described 1n connectlon with F gs.

1 and 2 except that the chamber below the wharffis subdivided into twoportions 23 and 24 by a partition 25 above which thewharfis providedwith an imperforate intermediate portion 26*. The subdivision 23 of thechamber is connected with the fan by external connections 26, and thesubdivision 24: of the chamber is connected with the fire tubes of theboiler, by an external connection 27 and a Atits discharge end the cokevided finger gates 30 which arerake-shaped structures having spacedupwardly projecting teeth. 1

In :use, assumingthe Wharf to be fully charged with coke, inert gas iscirculated up- .ward' through the righthand portion and downward 7through the lefthand portion. When the righthand portion is sufficientlycool, the finger gates are turned into the position shown and therighthand portion dis charged, then the lefthand portion is permitted tomove toward the right by turning down the gates and a new batch of hotcoke is introduced at the lefthand end. The obj ect of this is tomaintain a uniform and continuous generationof steam. 1

It will be obvious to those skilled in the art to which the inventionrelates that modifications may be made in details of construction andarrangement and matters of. mere form without departing from the spiritof the invention which is not limited to such been cooled 'to thedesired lower temperature, the circulation of matters or otherwise thanthe prior art and the appended claims may require.
